Continental Finance Company, LLC Credit Card Complaint

Continental Finance Company, LLC Credit card department,

Late fee Nevada

I would like to file a complaint against Verve MasterCard Company, due to the extremely high late fees and interest rate. I have tried to contact these people to work that out and it looks like every month they are taking on over hundred dollars worth of fees that is way too high for any credit card I own for credit cards and none of them is this high, please help!!!
